[0002] Hose is a kind of pipe widely used in industry, agriculture and household for transporting liquid, gas and solid particles. Hose is mainly composed of rubber and reinforcing materials, and is processed through a specific production process. When producing hose, a hose extruder is required. The outer surface of the hose produced by the hose extruder is mostly smooth, but the inner surface of the hose is less smooth, with many burrs and grooves, and needs to be polished before normal use.

[0003] In the prior art, the hose produced by the hose extruder is usually polished and cleaned on the inner and outer surfaces of the hose using a polishing machine to increase the smoothness of the hose surface. However, most of the existing polishing machines move the grinding roller into the interior of the hose and then drive the grinding roller to rotate through the motor to polish the inner wall of the hose. Since different types of hoses have different inner diameters, it is necessary to replace grinding rollers of different sizes when polishing different types of hoses, which increases material consumption, thereby increasing the cost of use and reducing work efficiency.

The electric cylinder 5 is used to provide power to drive the moving frame 6 to move left and right. A roller 7 is arranged at the bottom of the moving frame 6. The number of rollers 7 is set to be multiple, and the bottom of the roller 7 is in contact with the top of the base 3. The moving frame 6 is supported and lifted by the roller 7, so that the moving frame 6 is more stable when it is displaced. At the same time, rolling friction is used instead of sliding friction to reduce friction resistance, which is beneficial to reduce wear and energy consumption, and also reduces noise generation.

[0031] Reference Figure 1 - Figure 3 The polishing mechanism also includes a stepper motor 8, which is fixedly mounted on the inner wall of the mobile frame 6. The stepper motor 8 can accurately control the rotation angle of its output shaft, which is convenient for adjusting the rotation speed and frequency of its rotating shaft. It can be adjusted according to different production requirements and has good adaptability. The left side of the output shaft of the stepper motor 8 is fixedly connected with a rotating shaft 9. The polishing mechanism also includes a frame 10, which is fixedly mounted on the left side of the rotating shaft 9. The stepper motor 8 drives the frame 10 to rotate by driving the rotating shaft 9. The rotating shaft 9 penetrates and is rotatably mounted on the inner wall of the mobile frame 6. The polishing mechanism also includes a sleeve 11, which is sleeved on the outer surface of the rotating shaft 9. The sleeve 11 is set to be a hollow cylinder. The central axis of the sleeve 11 coincides with the central axis of the rotating shaft 9. The sleeve 11 is fixedly mounted on the left side of the mobile frame 6. The polishing mechanism also includes a circular plate 12, which is set It is a flat cylinder, and the circular plate 12 is fixedly mounted on the left side of the sleeve 11. The left side of the circular plate 12 is fixedly connected with a gear ring 13. The polishing mechanism also includes a rotating rod 14, which penetrates and is rotatably mounted on the inner wall of the frame 10. The number of rotating rods 14 is set to two groups, and the two groups of rotating rods 14 are arranged perpendicular to each other. The circumferential surface of the rotating rod 14 is fixedly connected with a bevel gear 15, and the bevel gear 15 and the gear ring 13 are meshed. When the frame 10 drives the rotating rod 14 to rotate, due to the cooperation of the bevel gear 15 and the gear ring 13, the rotating rod 14 rotates around the central axis of the rotating shaft 9 and also rotates around its own central axis. One end of the rotating rod 14 is fixedly connected with a cleaning brush 16 for cleaning the inner wall of the hose 22. It is worth mentioning that the device is suitable for polishing and cleaning hoses 22 with larger diameters. The other end of the rotating rod 14 is provided with an adjustment mechanism.

[0032] Reference Figure 4 The adjusting mechanism includes a sliding rod 17, which is slidably mounted on the inner wall of the rotating rod 14. The sliding rod 17 slides along the axial direction of the rotating rod 14. The end of the sliding rod 17 away from the rotating rod 14 is fixedly connected with a polishing head 18 for polishing the inner wall of the hose 22, which is used to remove burrs on the inner wall of the hose 22. The adjusting mechanism also includes a control block 19, which is slidably mounted on the inner wall of the rotating rod 14. The control block 19 is elastically connected to the inner wall of the rotating rod 14 through a spring 20. The spring 20 applies an elastic force to the control block 19 toward the inside of the sliding rod 17. A control groove 21 is opened on the surface of the sliding rod 17. The number of the control grooves 21 is set to multiple, and the multiple control grooves 21 are arranged on the surface of the sliding rod 17 in a straight line with equal intervals.

[0033] Working principle: When in use, start the hose extruder 1 to extrude the hose 22 from the right side of the extrusion tube 2, then start the power supply of the electric cylinder 5, the electric cylinder 5 works to push the moving frame 6 to move to the left, and drives the cleaning brush 16 and the polishing head 18 around the rotating rod 14 to extend into the interior of the hose 22.

[0034] Then, the power supply of the stepper motor 8 is started, and the stepper motor 8 drives the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the frame 10 to rotate. The rotation of the frame 10 drives the cleaning brushes 16 and the polishing head 18 on both sides of the rotating shaft 9 to rotate around the central axis of the rotating shaft 9. At the same time, since the rotation of the rotating shaft 9 will also drive the bevel gear 15 to move on the ring gear 13, the rotating shaft 9 will also rotate when it rotates, so that the cleaning brush 16 and the polishing head 18 will continuously rotate around the central axis of the rotating shaft 9 when cleaning and polishing the inner wall of the hose 22, thereby increasing the polishing range, reducing the dead angle of polishing, and ensuring the smoothness of the surface of the hose 22.

[0035] During the polishing process, the electric cylinder 5 operates to move the cleaning brush 16 and the polishing head 18 in the axial direction of the hose 22, so that the inner surface of the hose 22 in the left and right directions can be polished, further improving the polishing range and effect.

[0036] When polishing and grinding the hoses 22 with different inner diameters, the control block 19 is pulled outward so that the control block 19 overcomes the elastic force of the spring 20 and moves in the direction away from the sliding rod 17 until the control block 19 is completely separated from the inside of the control groove 21. At this time, the sliding rod 17 can be pulled unimpeded. After adjusting the extension distance of the polishing head 18 according to the inner diameter of the hose 22, the control block 19 is released. The control block 19 will be reinserted into the inside of the control groove 21 under the elastic force of the spring 20, and the polishing head 18 on the sliding rod 17 can be fixed, thereby improving the stability of the polishing head 18 during the polishing process and ensuring the effect of the polishing process.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
